When using `@DebugDescription`, only allow use of [LLDB Summary
Strings](https://lldb.llvm.org/use/variable.html#summary-strings) syntax from
`lldbDescription` properties. When `@DebugDescription` is applied to existing
`debugDescription` properties, escape any `$`, as the output of `debugDescription` is
never interpreted by LLDB.
Depends on #75305
